Common questions
Are decimal worksheets really free?
Yes. The Free plan lets you generate up to 30 worksheets per month at no cost, with a watermark. Paid plans start at $6/month, remove the watermark, and allow unlimited generation.
Can I get Thai-language decimal worksheets?
Yes. Switch the language to Thai and word problems adapt automatically — Thai names, baht currency (฿), and natural Thai phrasing. The decimal layout and column format stay identical so worksheets work in bilingual classrooms too.
How is this different from an AI worksheet generator?
AI generators like ChatGPT can produce rounding errors or wrong decimal answers (hallucinations). MathPrepAI builds every problem from its exact answer using SymPy, a professional symbolic math library, then verifies the result before you see it. The answer key is guaranteed correct.
Can I control how many decimal places appear?
Yes — use the difficulty level. Easy uses one decimal place (tenths), Medium adds hundredths, and Hard introduces thousandths and multi-decimal operations. Combine that with the problem count and language to create exactly the worksheet your class needs.
